Specification forming part of Letters Patent No.

'177,49 l, dated May 16,1/876; application filed September 20, 1875.

To all whom it may concern: y Be it known that I, SAMUEL C. FOX,- of Pittsburg, in the county ot' Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rolls and Conductors for Bolling Metals; and I do hereby declare the following to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawing, forming a part of this specification, in which-5' Figure 1 is a plan view of a series of hooprplls and conductors'embodying my invention. Fig. 2 is a longitudinal verticalsection of two sets of rolls and the conductor between them,

showing the apparatus for feeding the iron from one set to the other; and Fig. 3 is an end view of the conductor.

Like letters of reference indicate like parts in the several figures. My invention relates to the construction and arrangement of the rolls and their conductors, Ste., for rolling hoop and other iron. To enable others skilled in the art to make scribe its construction and operation.

A B represent two of a series of tongueand-groove hoop-rolls, between each pair of which is a conductor, C D, so arranged as to receive the iron from one `pair of rolls and to Each pair of rolls in the series is composed of one roll, grooved as shown at a, and another provided with a collar or tongue, a', which works into the groove of the first-named roll. These rolls I arrange in series, the alternate pair of rolls having the tongue and groove'reversed, as, for instance in the pair of rolls A, and in the pair forming the next in the series to the pair B. The tongue or collar a is in the upper roll,

' while in the pair B the groove a. is Yin the upper roll. VBy this arrangement of the rolls Vthe turning of theiron at each pass is Vavoided and b oth time and labor saved, as this work hasL heretofore been done by hand.

G `D are aseries of conductors arranged be tweenthe rolls so as toreceive the iron from one pair and conduct ity.to the next. VThese conductors O D rest upon the bearing-barsd upon th'e housings A4 B. Parallel to and near to each pair of rolls A B, I arrange the shafts E journaled in the bearings F, and provided with the belt-pulleys E' and dri'vingpulleys G for imparting motion to the same. Upon the pulleys E is placed thc chain-belt or carrier H, for carrying the iron from one set of rolls to thenext. At regular distances upon the belt H I place the cleats h, which E', by which means power is imparted to the belt H. This belt or carrier H forms the bottom or lower part of the conductor, and fits against the inner sides or ledges c3, and together with them forms three sides of the box through which the iron passes. Power is applied to the shafts E and pulleys E through conductors are preferably closed by top plates C to prevent the iron from twisting out of the trough or conductor; but as the hoop may at times buckle, on account of the variation of the. circumferential speed of the rolls it is necessary to make provision therefor. This I dobyiitting the top plate c loosely in guides czrestjng upon the ledges c3, or in any other suitable way, upon the upper part of the con# ductor, and holding it in position byy means of springs cl bearing upon the plate c, 'or in a similar Vsuitable manner. The advantage of springs is that while the plate c is capable of yielding, should the iron buckle, it will still be forced back by the springs c1 in such a manner as to regulate the feed of the iron to the succeeding pair ot rolls. If the pressure of the iron upon the plate c is great enough yit will overcome the force of the springs c1, press the plate out of the guides c2, and thus escape from the conductor without damaging the conductor in any way. This plate c rests upon the ledges c3, before mentioned, which form the sides of the box through which the iron passes. By making these sides of different widths, conductors may be made to suit the different sizes of iron to be rolled.

is as follows: Theiron is fed from the trainrolls to the rst rolls ofthe series, as at A, from which it -passes into the conductor C. The force of the rolls A drives the iron into the conductor untilit rests upon the chain-carrier H, by which it is automatically carried for- ;rrron,

'catch in corresponding slots in the pulleys the pulleys Gr in any suitable manner- These The operation of my rolls and conductors ward and fed into the rolls B, through which it passes onto the conductor D, and so on through the whole series of rolls. As the tongue and groove upon the second pair of rolls are the reverse of the first, the iron will not need to be reversed, so that one set of attendants is dispensed with, and from the second pair of rolls the hoop is passed by a second conductor to a third pair of rolls having the tongue and groove arranged like the first pair, and so on through any required number of rolls. Any tendency of th'e iron to buckle will be corrected and obviated by the selfadjusting top plate c, and if the force of the iron be too great the plate will be pressed out of the guides 02, and the iron will escape from Jthe box without damaging the'conductor, as it might had no provision been made therefor.

The advantages of my invention are that to a great extent the operation is automatic, and the usual number of attendants required is greatly reduced. v

What I claim, and desire to secure by Letters Patent, is-

1. The combination of two or more pairs of hoop-rolls, the tongues and grooves of the alternate pairs being reversed, and intermediate conductors having relief tops, substantially as and for the purpose specified.

2. The combination of two or more pairs of hoop-rolls, the tongues and grooves of the alternate pairs being reversed, and intermediate conductors provided with chainbelt or traveling bottoms, substantially as and for the purpose specified.

3. In combination with two pairs of workrolls, the interposed conductor having a travcling bottom, substantially as and for the purpose specified.

4. A conductor for feeding metal to or between rolls provided with a reliefl top, and having its bottom formed by a chain-belt or carrier, substantially as described.

In testimony whereof I, the said SAMUEL C'. FOX, have hereunto set my hand.
